The Elektor Mini Counter

Retronics series

Just shy of forty years ago, Elektor published two frequency counter project articles in the June 1978 issue. The ‘µP counter’ concept was forward looking. For professionals there was the ¼ Gigahertz Counter, and for hobbyists the Mini Counter. Readers could purchase ready-made PCBs for both of these projects from the Elektor Printed-circuit Service (EPS).
